Mac/iPhone/iPad: Things, a GTD-inspired to-do manager, has long been a well-polished and feature-rich way to manage your to-dos, but until now making sure everything stays in sync on the go has been difficult. Things 2 brings a number of updates to the Mac, iPhone, and iPad apps, and also features cloud sync to keep all of those to-dos organized and up-to-date across all of your devices.

In addition to syncing tasks in the cloud—which is a simple on/off switch in the new app—Things 2 brings some visual polish to all of the Things apps, the ability to use Siri to add to-dos on the iPhone, a new scrolling calendar on the iPhone and iPad, a new "Daily Review" list of things you want to remember but aren't exactly due on a specific day for the Mac, and more.

Things fans (and we know there are some of you) have been waiting for this update for a long time, and if you've paid for the app in the past, the new version is a free update for you. If you're not a Things user, the price of entry is pretty steep: The Mac app will set you back $50, iPhone $10, and iPad $20. Still, fans of the app love it and say it's worth the money. If the price tag is a bit much for you, free app Wunderlist is our favorite for Mac, Windows, Linux, and even Android and a decent alternative. Even if you don't care for Wunderlist, you have plenty of options. If you're a Things user, let us know what you think of the update in the discussions below.
